These operating instructions contain information about the
transport, installation and commissioning of STOBER EZ,
EZHD, EZHP synchronous servo motors and EZS, EZM syn-
chronous servo motors for screw drive.
For further details, see the catalog with the ID 442437.
In the event of any unclear points, we recommend that you
contact STÖBER with the model designation and serial num-
ber, or have the installation and maintenance work carried out
by a STÖBER service partner.

Operation in accordance with its in-
tended use
Synchronous servo motors must be used exclusively for op-
erating machines and systems together with servo inverters.
Stay within the limits defined by the technical data.
Do not use synchronous servo motors in potentially explosive
atmospheres.
For reasons of operational safety, motors may only be used
for the single application for which they were projected.
Any overload on the drives is considered unintended use.
The information and instructions in these operating instruc-
tions must be precisely followed to ensure that claims submit-
ted under the warranty will be honored. If modifications are
made to motors, warranty claims will be rendered void.
Comply with the safety instructions in these operating instruc-
tions and in all supplementary documents for the synchro-
nous servo motor and other components such as gear units
and servo inverters.

Technical data
The technical data for synchronous servo motors, geared mo-
tors and servo inverters that are used is indicated on the rel-
evant nameplates.
Acceleration / shock load in operation:
The following value for the shock load indicates the value up
to which the motor can be operated without loss of functional-
ity: 50 m/s² (5 g), 6 ms (maximum value as per DIN EN 60068-
2-27).
Brace the motor connection cable close to the motor so that
vibrations of the cable are not transferred to the motor.
When connecting the motors to drive units such as gear units
or pumps, take into consideration the permissible shock loads
and tilting torques of the units.
Designs:
IMB5, IMV1, IMV3
(DIN EN 60034-7)
Protection class:
EZ, EZHD: IP56
EZHP: IP56 / IP66 (option)
EZS, EZM: IP40
(DIN EN 60529)
Protection class:
I
Thermal class:
155 (F) (DIN EN 60034 / VDE 0530)
155 °C, heating ΔT = 100 K
Surrounding
temperature:
-15 °C to +40 °C (with water c5
°C to +40 °C)
Installation altitude: up to 1000 meters above sea level
Cooling:
For IC 410 convection cooling;
or optional IC 416 convection cooling
with forced ventilation (DIN EN 60034-
6), see 2.4.1;
or optionally for water cooling in the A-
side motor flange, see 2.4.2
Surface:
Black matte as per RAL 9005
Please note! Repainting will change
the thermal properties and therefore
the performance limits of synchronous
servo motors.
Vibration intensity: as per DIN EN 60034-14 degree N
(half wedge balancing for shafts with
key).
Winding:
Three-phase, single-tooth design
Connection
method:
see motor connection diagrams
Information
If brakes are installed, the holding torques may
be reduced by the shock load!
